IMPROVEMENT INMEANS FOR VENTILATING SEWER-PIYPES AND WATER-CLOSITS.tV

Specification forming part of Letters Patent No. 218,799, dated August19, 1879; application filed March 29, i879.

To all whom it may concern:

Be it known that I, LORENZO ULLO, of South Orange, in the county of`Essex and State of New Jersey, have invented certain new and usefulImprovements in Means for Ventilat ing Sewer-Pipes and Water-Closets, ofwhich .trap becomes foul, and unless provision is made for carrying 10ftgases accumulating above the water in the trap they will pass upwardinto the dwelling.

The object o f the present invention is to provide for properlyVentilating waterclosets,

commodes, and the like, and also the portions of sewer or wastepipesqwhich are above the traps. f,

fTo this endthe invention consists in the combination, with awater-closet, of a trap, a waste-pipe 'leading therefrom, a pipe oropening independent of the main opening at the mouth of the closet forthe admission of air to the closet fromwithin the building in which thecloset is situated, and an upwardly-extending pipe orpassage for theescape of gases leading from said closet above said trap separate fromand independent of said waste-pipe,

whereby a circulation of air is maintained in the closet, and the sameis thoroughly ventilated.

In the` accompanying drawings, Figure l .represents acentral verticalsection of a 'waf ter-closet embodying my improvements, and Fig. 2 aplan thereof. Fig. 3 is a central vertical section of the basin or valveof said closet detached from theother parts. Fig. 4 issa verticalsection of a portion of a building provided with waterclosets andsewer-pipes embodying my invention. Fig. 5 is a vertical section of abuilding, showing amodied form of my invention; and Fig. 6 is a plan,partly in section, of a modication of my invention.

Similar letters of reference designate corresponding parts in all'thefigures.

Referring, first, to Figs. l, 2, and 43,A designates the bowl, and B,the basin,fof av watercloset embodying my improvements. C des ignates avalve (here shown as` consisting of an ordinary slide-valve) for closingthe outlet of the basin B and preventing the passage of gases upward.

Any other description of valve may be employed, or in lieu thereof ahinged pan for containing water and sealing the outlet of the said basinmay be employed. Thesedetails are .not here represented, as they form nopart of the present invention.

A' designates the outlet of the bowl A, which communicates with awaste-pipe, preferably provided with a trap of the ordinaryconstruction. The bowl A is provided with an open ing, a., from which apipe or passage extends upward, and communicates with the externalatmosphere.

D designates a pipe or passage communieating with the bowl A, throughwhich air passes into the same from theapartment in which the closet issituated.

By means of these two pipes or passages a continuous current of air ismaintained through the water-closet, and any noxious gases emanatingfrom the contents of the water-closet or trap are carried off throughthe outlet-opening a. I prefer to vmake the pipe or passage D of suchlength as to extend nearly to the floor of the room in which the closetis situated, as by that means the heavy and impure Vair at the bottom ofthe room will be drawn off. To provide for a more active circulationthrough the closet a gas-jet may be kept burningl in the pipe or passageD 5 or the` supply of air may be drawn from the heated air near theceiling of the kitchen, if the building in -which the closet is used isa dwelling house.

Fig. 4 represents a number of water-closets arranged on different iioorsof a building.

The closets E E are of the kind l generally known as hopper closets, asthey are not .provided with pans like the one previously described.

I have here represented these closets as com- H designates pipes orpassages extending vertically through the building, with which thegas-outlets of several closets may communicate, and through which gasesmay pass upward to the atmosphere.

For the purpose of economy the gas-outlets of several closets maycommunicate with a chimney-line, which, if the iiue is used as asmoke-flue, will greatly aid the circulation of air through the closets.The pipe or passage for the supply of air to the closets may be carrieddown, and the supply ot' air drawn from a door below that upon which thecloset is situated, as represented at I, Fig. 4.

In Fig. 5 l have represented the waste-pipes b, c, and d of awater-closet, a wash-basin, J, and abath-tub, K, as all extendingdownward into a receiver, L, placed in the cellar of the building. Thisreceiver communicates through a trap, M, with a sewer or waste pipe, N.

O designates the pipe f'or the admission ot air to the receiver, and P apipe or passage through which the air and gases pass upward to theatmosphere.

Fig. 6 represents the receiver L as provided upon its side with achamber or chest, I, for the reception of a series of waste-pipes.

It is obvious that as the pipe or opening D, through which air passesinto the closet from the room, is independent of thc main opening at themouth ot' the closet, proper ventilation may be insured without leavingthe mouth of the closet open.

It will be understood that as the pipe through which the gases pass isentirely separate from and independent of the waste-pipe, air and gasesmay pass uninterruptedly through said pipe, which would not be the casewith a waste-pipe passing upward and ventilated at the top, as then theow of gas would be stopped by water passing through the pipe, and thewater would compress the gas below it and cause it to pass into lowerrooms if the discharge into the waste-pipe were from an upper story.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination, with a water-closet, of a trap, a waste-pipe leadingtherefrom, a pipe or openingindependentof the main opening at the mouthof the closet for the admission of air to the closet from within thebuilding in which the closet is situated, and an upwardly-extending pipeor passage for the escape ot' gases leading from said closet above saidtrap separate from and independent of said wastepipe, substantially asspecified, whereby foul gases are prevented from passing upward by thewater in the trap, and the gases accumulatin g above the water in thetrap are carried away and prevented from passing into the room in whichthe closet is situated.
